AbstractSolar cells offer a clean method of making electricity straight from sunshine. In this task you will build an easy circuit and experimental setup to research whether or not the energy result of a solar mobile modifications with ambient temperature.
The goal of this task is always to determine the way the power result of a solar cellular varies with background heat.

Solar panels (or photovoltaic cells) are products that will create electrical energy right from sunshine. You could have seen arrays of solar cells on a roof in your neighborhood, or a much smaller variety powering an emergency phone along a highway. Within project you will definitely research how energy result from a solar cell changes with temperature.
Terms and principles
To get this done project, you need to do research that enables you to comprehend the following terms and concepts:
- Solar (or photovoltaic) mobile
- Open-circuit voltage
- Short-circuit existing
- Do you consider solar cells function better when they're hot or cool?
- Do you think the voltage output of a solar mobile will increase or reduce as soon as the temperature increases? What about the existing?

- With this web page it is possible to develop digital circuits with electric batteries and resistors, after that examine your circuit by putting a switch to light up a bulb. If there's excessively existing, the virtual light bulb blows up; inadequate current, while the bulb won't light. When you get the existing right, the bulb glows brightly.

Materials and Equipment
- Infrared thermometer. A few infrared thermometers are available from Jameco Electronics however they are relatively costly. Cheaper infrared thermometers are available from Amazon.com.
- Light source. If possible, can be done the task outside in sunlight. If you do the task inside, make use of a high-wattage incandescent light bulb (preferably 150 W) or an equivalent CFL or LED bulb. (Note: because of the spectrum of light emitted, solar cells try not to generate just as much power from CFL or LED bulbs, but you will still be capable of making dimensions for purposes of a science project).
- Quart-sized resealable plastic case
- Hot and cold plain tap water

Experimental ProcedureNote before you start: This research fair task requires that connect a number of devices in an electrical circuit. Fundamental assistance can be found in the Electronics Primer. However, if you fail to have expertise in piecing together electrical circuits you could find it helpful to have an individual who can respond to questions and help you troubleshoot if the project isn't working. A science teacher or parent could be a good resource. If you need to discover another mentor, try to look for someone who has hobbies like robotics, electronics, or building and repairing computer systems. You may have to work the right path as much as this task by you start with an electronics task that less level of difficulty.
- Set up your experiment, as shown in Figure 1.
- Set-up your lamp a set length from where you will test the solar mobile. If you are doing the task outside, arranged your experiment in an area with direct sunlight.
- Link your multimeter's leads to the solar power mobile's alligator clip leads. With this research, you need to toggle between reading voltage and present. If you'd like assist using a multimeter, read the Science Buddies Multimeter Tutorial.
- Cover the subjected solder joints on the straight back of the solar power mobile with electric tape. This may help protect the panel from condensation when you use it top of a bag full of ice water.
Figure 1. Experimental setup to measure just how temperature affects the production of a solar power cellular. In this image, the solar power mobile is cooled by a bag of ice water.
- Prepare a data dining table within laboratory notebook with articles to capture solar power cellular heat, open-circuit voltage, and short-circuit current.
- Fill a resealable plastic bag with ice water. Make an effort to make certain there is minimal atmosphere left in bag. This may make certain the solar cell is within direct connection with the chilled water, rather than sitting in addition to an air bubble that'll behave as an insulator.
- Ready to position the solar power cellular directly on the top of synthetic bag. The solar power mobile will begin to sweet quickly, so that you will need to prepare yourself to simply take dimensions.
